A Complex and Not so Complex Response.

More Complicated
How does teen parenthood affect the future lives of young women and men?

This question feels complicated, people with or without children can already put themselves in this situation. Of course, this isn't a "yes or no" question, but could probably be talked about in many pages. It's along the lines of ethos, due to there being an ethical attachment to this question. So a writer will be able to identify and attach to a side to the issue.

 By stating that there is an affect on teens due to teen parenthood, you already have a vision in your mind of possible negative connotations. Granted, this question doesn't say anything negative about teen parenthood, but it suggests that there is still an affect from it.
What causes these teens to go through such an early parenthood? Whether it's consensual, forced, or just plain stupidity, there is always a reason for why these children are having children.

Hopefully, the student will explore possible positive affects from the teen pregnancy issue. No one is the same, and for the sake of not being bias, I feel the paper would benefit from both point of views. 

This question also will be answered differently between adults and teenagers. Most teens have no idea how this could affect another teen's future life, so will probably approach this as a research question. An adult will come at this question in a parental, and "experienced" way, and will probably answer much differently than a younger student would.

Less Complicated
Is it right for scientists to create new life forms?

Right off the bat, people can answer this in a yes or no fashion. This questions raises some ideological morals, and would cause the student to argue their own world views rather than facts. Of course, this may not be true with every student. But it's general enough for the students to easily answer the question. Hopefully, the student would take the time to define what constitutes a life form, and when or if there is a time when creating a life form is just. At that rate, hopefully the student is able to see that saying something is "right" is on a personal level, for there are many truths, not just one. This is an opinion question, and the student will have to understand this and try to bridge the gap between the two sides of the argument.
